XP-G Tint Greenish?

[recDNA]

Now of course there aren't many XP-G lights out there yet but my Quark Titanium CR123 X 1 has a distinctly greenish tint. I like White, would be happy with Blue-White, and would be shocked with warm white but I was surprised by green.

Is yours like that?

Is this a characteristic of the XP-G R5 or is it something about the Quarks that causes it?

Does it have this green tint even at the higher output modes?

It's most likely the LED that is the culprit and when driven at lower levels it makes the tint shift even more to green. So I guess you could say it has to do with both.

I recently build a Tower Module with a R5 sourced from Cutter
At first I thought it was my eyes, but yes it is definitely green :green:

BTW the R5 is being pushed at 1000mA

This may be way out in left field and I know binning does equal tint, but I've seen a few cases of XPG R4s being weirdly green.

Then ALL the new XP-G R5 lights will produce greenish beams?

The green is only obvious on lower modes for my Quark Ti AA.

I have at least 5-6 lights I've modded with XP-G's...binned R4 & R5
The tints have varied between them as well as power levels.
Some are almost pure white, others have a very slight blue, and the one in my T1A is just barely green.
Thats been my experiance so far.

The tint on my Quark 2x123 Tactical Ti is greenish on high, it has alot brighter hotspot than the Aluminum version. Hard to tell by this picture but you can tell its not cool white. Quark 2x123 on the left and the Quark 2x123 Ti on the right, both tactical versions.

Yes, all three of the Ti Quarks that I received are distincly "Coke bottle" green. I don't like it. Either by tint shift or pure volume of light, high and turbo are quite tolerable, but I don't use those much at all. I have to assume that the Preons will be the same and am holding off on those because of this.

Not necessarily. LEDs can vary in tint even in the same group.

So no, not all R5 will be green.

Thats ashamed, why cant they all be cool white Iam guessing that 99.9% of the people I talk to want cool white.

I like a little warm vanilla in my LEDs. I think I actually got lucky and received an R4 from nailbender that has that tint. I'll check the other two and see if they have any green.

I only notice a slight green tint in moon mode all other levels are very white.

 

[JamisonM]

With the two I have, one in a L2D-CE and the other in a 3D maglite being driven by an SOB1000, the only greenish tint I notice is in the L2D-CE's low mod. It's even less noticeable in it's medium mode. Beyond that it's not noticeable nor it is in the maglite.

 

[PeaceOfMind]

Maybe it's stupid of me to think this, but would having a bit of extra green in the beam (versus being more blue) make it easier to see green things outdoors (trees, plants, etc.)? Of course more neutral white would be even better at this, I'm just wondering about green-ish versus the cool-white blue-ish.

my Quark Ti also has a touch of green, but I mostly only notice it if I compare side by side with another light.

There is very little that we can do at this time as to the tint of the XP-G LEDs in all power levels. Cree has never been good to us flashlight manufactures as to our choice of tint bins or forward voltage bins like the other major LED manufacturers. When you order LEDs from Cree you can only order by one of three Kit numbers, and that Kit may contain any thing that Cree has produced. The Kit that they are currently shipping contains any one or more of 40 different tint bins. The Greenish bins are most likely 1S, 1T, 2S, 2T or 3S on the revised ANSI C78.377A Chromaticity curve. The preferred Kit includes only 4 tint bins; 2B, 2A, 2D and 2C. Good luck in getting that Kit at this time in the production cycle. If you have to hunt white walls than you may be disapointed until production exceeds demand. If you can be satisfied with the latest technology in LEDs for small pocket lights, with the most power or battery run time than the XP-G is what you want.

Like others have said, I notice the green in my beam only in moon and low modes. In turbo, it's very very white, and not angry blue at all. I think it's a good tint -- I'd rather have a dim green than a dim blue anyway, but that's just me..

If I set my Ti Cr123 on turbo and compare it's beam to ANY of my other led flashlights it looks distinctly green - not white. When I aim it at my aquarium neither the fish nor the wood nor the gravel look anything like the correct colors. Sounds like mine is worse than yours. Even without another flashlight on for comparison the turbo beam on my white wall looks like a sickly, yellowish green.

It's good to know other Quarks look better. My wife is thrilled with it and I haven't said a word about the odd color to her so I hope she doesn't notice it.

On this forum many if not most like warm white or white white. I actually LIKE cool white in fact it's why I switched from incandescents to led's.

Thanks. That's a very informed response. I'm happy to know that in the future I'll be able to get white XP-G's. I really like the floody beam profile and the large hotspot. The beam is beautiful in very way but color. No rings. Nice and bright. No donut.
